Re: [OSGeoLive] MapCache Permissions
Thanks both. I tested with /var/cache/mapcache and it works directly without any need to create folders/update permissions, which will simplify the install script a little. I'll make a new pull request with this path. Bas - where is the best place to find these details? Are there docs, or is it best to look at the packaging scripts?

Re: [OSGeoLive] MapCache Permissions
Hi Seth, I would recommend to move the mapcache folder to /usr/local/share/mapcache Best, Angelos On 7/24/19 6:04 PM, Seth G wrote: Hi, I'm currently testing the latest beta from http://aiolos.survey.ntua.gr/gisvm/dev/osgeolive-nightly-build163-amd64-38dc97a-master.iso with MapCache. There is a permssions issue causing tiles to return "failed to create directory /home/user/mapcache/tilecache..Permission denied" The https://github.com/OSGeo/OSGeoLive/blob/master/bin/install_mapcache.sh#L44 script runs the following: # make a folder for the tilecache abd set the owner to be www-data MAPCACHE_DIR=/home/user/mapcache mkdir -p "$MAPCACHE_DIR/tilecache" chown -R www-data:www-data "$MAPCACHE_DIR/tilecache" On the latest release the owner of /home/user/mapcache/tilecache is still "user". If I run these manually (with sudo) on the latest release everything works correctly. The Zoo installer also has a similar approach: https://github.com/OSGeo/OSGeoLive/blob/master/bin/install_zoo-project.sh#L77 It refers to ticket https://trac.osgeo.org/osgeolive/ticket/1850 which has discussions of folder locations for a tile cache. Should I update the install/configs to point to /var/mapcache/tilecache to keep the permssions? I presume ownership of the folder is changed in a later script, or is not advised.
